PLZ HELP MEEE EASY POINTS I WILL GIVE BRAINLIEST Which characteristics will prove that ΔDEF is a right, isosceles triangle?

segment DE is larger than segment EF, and their slopes are the same.
segment DE is larger than segment EF, and their slopes are opposite reciprocals.
The lengths of segment DE and segment EF are congruent, and their slopes are the same.
The lengths of segment DE and segment EF are congruent, and their slopes are opposite reciprocals.

DEF

Step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
